Distributed Energy Storage Aggregation Coordinated Regulation Strategy in Active Distribution Networks

As the power grid integrates a higher proportion of distributed energy resources, there remains a need to develop comprehensive regulatory strategies that optimize the economic operation of distribution networks and improve the capacity for integrating renewable energy sources.This paper introduces an innovative two-layer regulatory strategy designed to significantly reduce the operational costs of distribution networks and enhance the capacity for integrating wind and solar energy. The upper layer focuses on the coordinated scheduling of adjustable energy storage aggregator, in the lower layer of the strategy, a consensus algorithm is employed to swiftly and precisely relay instructions from the upper layer to the distributed energy storage systems within the aggregator. Through case studies, the effectiveness of this method has been validated, demonstrating its potential to enhance both the efficiency and economic performance of distribution networks.
